GLASS ELECTRIC HOT PLATE original Fild Nov. 5, 194s Patented Cet. 15, 1946 UNITED STATES PATENT OFFICE 2,409,244 GLASS ELECTRIC HoT PLATE John Bilan, Flint, Mich.

Original application November 5, 1943, Serial No. 509,063, now Patent No. 2,391,382, December 25, 1945. Divided and this application December 7, 1944, Serial No. 567,009

1 Claim. l

This is the division of application on burners Serial No. 509,063, led November 5, 1943, issued December 25, 1945, as PatentNo, 2,391,382.

The present invention relates to burners and has for its main object the provision of a burner constructed entirely of glass within which electric wire coil is imbedded, so that when electricity is passed through the coil the entire glassI is heated.

With the above general objects in View and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the kseveral views;

Fig. 1 is a top elevational View of the and Fig. 2 is a cross-sectional view on line 2-2 of Fig. 1.

Referring to the present drawing there is shown therein a. glass plate ID which is provided on its bottom with a plurality of integrally formed and concentrically arranged annular ridges II which constitute the support for said plate I0. Imbedded within said glass plate I is electric wire coil I2, which is distributed throughout the plane of said plate I0, the two ends of said coil I2 extending beyond the perimeter of said plate I9 and bound into cord I3 which connects with a conventional switch I4 and from there connects with the usual socket (not shown) which in turn connects with a sourceof electricity.

The wire in coil I2 is made of the usual high resistance metal so that the same may heat to a great degree of temperature when electricity is burner;

(Cl. 21B-37 passed therethrough. Glass used in plate I0 is of the pyrex type, which does not crack when under the inuence of a high temperature.

A plurality of transverse openings I5 is made in plate IG, in a spaced relation, transversely of the body of plate I (I and between the several strands of coil I2, for the purpose of providing draft through said plate I0.

When said plate I0 is placed upon a smooth surface, impervious to re, and rested therein by its ridges II, and electricity is open by switch I4, plate I0 will form a burner of high intensity upon which pots may ybe placed for boiling or heating the contents thereof.

The burner herein shown may be placed upon a metallic cylinder for supporting the same and for keeping the same out of Contact with objects pervious to re. When so supported one of the annular ridges II would either t within the cylinder or lbe disposed outwardly therefrom, thereby maintaining the burner against lateral shifting upon the support.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

A burner comprising a glass plate, an electric wire coil of high resistance imbedded therein, said wire coil including a plurality of strands concentrically arranged, and a plurality of annular ridges concentrically arranged and extending from one face of said plate, said plate being provided with a plurality of spaced openings transversely of the body of said plate, said openings being positioned within the several concentric areas in said plate dened by said strands.
